I would think you have some time to re-home any boys. They don’t have to go until they crow, and it takes two weeks to develop a crow (hilarious to hear them practicing). You can get more time by setting up a large dog crate with puppy pads in a garage and keep the boys in there every night til you find homes for them. If the blue chick in your avatar turns out to be a boy, I’m interested. From the comb it looks like 2 copies of the blue egg gene, so worth breeding.
